SAFETY APPARATUS.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed February 26, 1906. Serial No. 302,831-

of New York, have invented certain new and.

useful Improvements in Safety Apparatus, of which the following is a specification, taken in connection with the accompanying drawing, which forms a part of the same.

This invention relates to safety apparatus particularly adapted for application to locomotives and electrically-propelled cars.

The accompanying drawing illustrates diagrammatically the embodiment of this invention upon an electrically-propelled car.

In the illustrative embodiment of the invention shown in the drawing 1 is a track device or trip pivoted at 2 and fixed upon the road-bed to swing into and out of operative position and is usually used in connection with a semaphore. (N'ot shown.) When this semaphore is set at danger, the trip 1 is in position (shown in full lines) and -is 3, mounted upon the end of the hollow pistonrod 4., working within the cylinder 5. This cylinder is divided into two parts by the plate 6, which is firmly secured upon the interior of the cylinder by the screws or other fastening means 7. The p ston-rod 4 asses through an air-tight aperture in the p ate 6,

and its upper end carries a piston 8. In communication with a lower portion 9 of the cylinder 5 is a train-line pipe 10, within which is mounted the emergency-valve 11, which is normally seated in the position shown in full lines by the train-pipe pressure, but when properly operated in the manner hereinafter to be described movesfrom the position shown to the stops 12 12. The upper portion of the cylinder 5 is connected below the piston 8 by means of pipe 13, pipe 14, three-way valve 15,v

pipe 16, with the main reservoir 17. Pipe 13 15 also in communication with pipe 18, valve 19, and with the upper portion of the emergency brake-cylinder 20. The upper portion of cylinder 5, above the piston S, is connected by means of pipes 21 22 and three way valve 15 with the main reservoir 17 and is normally charged with air under pressure therefrom when the valve 15 is in position. (Shown in full lines.) Pipe 22 also connects with the lower portion 23 of the cylinder 20, which is also normally charged with air by means of pipe 24, This three-way valve 15 may be of any well-known type.

Within the cylinder 20 and adapted to re- ;ciprocate between the openings of pipes 18 and 24 is mounted a piston 25, having a rod piston 25 upward away from the opening of pipe 24. The piston-rod 26 is elongated and passes though a check-cylinder 28. Mount ed upon the lower portion of the piston-rod 26 is a second piston 29,having a flap-valve 30. Oil is usually placed within this check-cylin der through the opening 31, which is closed by a cap 32.-

A part of my apparatus also includes the ordinary brake-cylinder 33, which operates the brake-shoes in the usual well-known manner. To obtain some of the fluid-pressure used in operating the brakes to simultaneously shut off the motive power when the brakes are applied, I connect pipe 34 to the brake-cylinder and at its opposite end connect it with the cylinder 35. Within this latter cylinder there is a piston 36, having a rod 37, to the outer end of which is connected a contacthead 38. Mounted within the cylinder on the opposite side from the opening of pipe 34 is a spring 39, which normally presses the contact 38 outward to complete the circuit between the wires 39 40, and it will be seen that when pressure enters the brake-cylinder 33 this c rcuit is broken by the cylinder 35. These wires 39 and 40 are a part of the ordinary multiple-control circuit 41, which passes through the ordinary controllerboxes 42 42, which operate in a well known manner by the control-switches 43 '43. Two terminals 44 44 of this multiple-control circuit 41 are located adjacent to each other and ada ted to be electrically connected by means 0 the contact-plate 45, carried by the valve-arm 19, for the purpose hereinafter to be described. The multiple-control circuit 41 is shown broken at 46 and 47 to be connected with the master-controllers of the several cars making up the train all in a well-known manner. 3

The operation of the parts so far described is such that if the engineer or motorman fails to see the danger-signal the trip 1 will engage the destructible cap 3 as the car passes over this portion of the track and will break the same, permitting the air-pressure to escape from the train-line pipe 10 through 26 and a spring 27, which normally forces the .next block without irnsettiifiythea signal;

the lower portion 9 of'the 'cylinder'o, and thence through the hollow piston-rod 4 by means oi the 0min? This will in! mediately apply the rakes of the car in the well-known manner and cut oil the motive power by 0 crating the cylinder 35. It is often desira 1e, however, to permit the mo-v torman to pass by the danger-signal into tgrg this a plication the vertic .-movable portiono the safety apparatus the destmctibie cap, which is adapted to contact with the fixed trip 1, is raised and lowered into operative position by mechanism which will now be described.

With the in the position shown in full lines the motorm'an moves the valve 1-5 into the position shown in dotted lines,- which exhausts the pipes 21 24 and upper part of cylinder 5 and lowerpart of cylinder '20 and at the i same time permits the fiuidpreseure to how I from the main reservoir in the direction indicated by the arrows up through pipes 16, valve 15, ipe 14, ipe, 13, around into the c linder 5 neatht e piston 8 and will in an 0 times manner cause the some to move i pipe 18 throu from the position shown until the piston contacts wit the lugs 49 49. At the same time thefiuid-pressure is 0 rating to more the piston 8 a portion of t e same will flow into valve 19 into the upper portion of the cy dcr 20 above the piston 25.

1 The. pressure in this cylinder causes the pistermed 26 to move against the action of the spring 27 and in the retarding-cylinder 28 wiii force the oil contained within the same to how through the by-pass 50; The openings of this by-pass are so proportioned as to require an ap reciable interval of time to elapse, about ve or ten seconds, before the piston-rod 26 reaches its extreme downward movement, where its end 51 is adapted to contact with the head 52 of the emergencyvalve 11 and immediately open the same. When it is desired to reset the safety device, the handle of the valve 15 is moved into position, (showninfull'linesQ which exhausts the pipes 13 18 and that portion of the cylinders 5 and 20 communicating with the same and permits the air-from the main reservoir 17 to again flow through the three-way valve 15, the pipes 22, 24, and21 to the respective portions of the cylindersfi and 20, which will cause the destructible mp3 to be lowered into a position where it is adapted to be operated by the next succeedirag trip l should the the same time the piston 25 is moved in the direction indicated by' the arrow it carries with it the piston-rod 26, the piston 29, and the flap-valve 30, which in this movement of the parts swings downward and permits the oil to pass readily through the o ening 53 into the lower portion of fthe checfi-cylinder i done, the piston-rod 4, on which is nger-signal. At

saaaee 28 without forcing the same to flow through the by-pass 50. It will be readily understood that this arrangement oi by-pass and, flap-valve retards the downward movement of the piston-rod 26 and its head 51, but per mits of the parts being readily retracted vwithout any appreciable retarding action.

In my safety apparatus,when it is desired the destructible cap 3 into an inoperativa position to escape the trip 1 there IS an appreciable interval of time before the head 51 of the iston-rod 26 contacts with the head 520'? t semergency-valve 11, due to the check-cylinder retarding the movement of this piston-rod. This is a very valuableimvalve 19 and contact piece 45 provement in the art, as it permits a motorman who has stopped his train within a short distance of the trip 1 and who desires to pass the same to do so without cutting ofi his motive power in operating his valve 155, permitting the fiui pressure to pass into the pipes 13 and 18 and cylinders 5 and 20 in the manner previously described. When this is forced the destructible cap 3, is immediately ppwardand the piston-rod 26 and sad 51 ewise immediately start to descend. The latter, however, is retarded, as previously described so that the motorman can byhis controller-handle 43 apply power to his car, so as tosee the fixed trip'l. If he then immedimounted ate y turns the three-way valve 15 so as to exhaust pi es 13 and 18 and the respe tlive portions 0 cylinders 5 and 20,with w ch they communicate, and at the same time permit air under pressure to pass-thro h'prpes 16, 22, 24, an 21 into the c 'nders 5 and 20, the destructible cap 3 Will be immediatel placed in position where it can be operate b the next fixed trip 1, and at the same time t e head 51 'of the piston-rod 26 will be stopped in its descent toward the head 52 of the vave be done without interrupting the control of the motive after operating the three-way valve 15 so as to raise the destructible cap 3 into its inoperativeposition the motorman applies ower to the car, permitting it to pass a'fixe stop 1, and forgets to move back the three-way valve 15 into the position shown in full lines, in about five or ten seconds the head 51 of the piston-rod 26 will contact with the emergency-valve 11 and instantly bring the train to a full stop, and at the same time fluidressure will pass into the brake-cylinder 33 wer of the train. If, however, 7

11 and retracted,'all of which will Y 1n the well-known manner in this art, and a portion of the samewill pass through pipe 34 tothe cylinder 35', causm move against action of t e spring 39 and move the contact-piece 38, thereby breaking the plston 36 to the electrical connection in the multi le-control circuit 41. By this construct on the motorman has full control of 1115 tram even trol continues for about sutlicient time to permit him to operate the valve 15, so as to again place the safety. apparatus into its operative position, failure to do which will, as previously pointed out, after an interval of five or ten seconds bring the train to a full stop by the opening of the emergency-valve 11 and cutting off the motive power.

If my safety tric train'of two or more means of a multiple-control circuit, the motorman leaving, say, car 1, to operate the train from what was the last car, he will first close the valve 1!) to break the connection of the upper portion of cylinder 20 with the main reservoir 17 through the pi es 14, 16, and 18. At the same time that t us is done the multiple-control circuit 41 is also interrupted by the plate45, carried by the valve 19, being moved from the contacts 44 44. The three-way valve 15 is then operated so as to place the main reservoir 17 in communication with the cylinder 5 through pipe 13. This position of the valves 15 and 19 permits of the piston 8 in the cylinder 5 being forced upward without, as is normally the case, at the same time forcing downward the piston 25 in the cylinder 20. When the 1parts are in this position, the spring 27 will cop the head 51 of the piston-rod 26 from contacting with the emergency-valve 11. This throws out of operation the safety apparatus on this car as the other safety apparatuses on other cars should have been thrown out, except the one on the car from which the train is being controlled. To operate the train from what has been the last car, the motorman must open the valve 19 so as to place the cylinder 20 in communication with the main reservoir 17 throughthe pipes 14 and 16 and three-way valve 15 and at the same time make electrical contact between the contact-pieces 44 44 of the multiple-control circuit 41 and the plate 45. The valve 15 is then operated to exhaust the pipes 13, 14, and 18 and to place pipes 22,21, and 24 into communication with the main reservoir, so as to permit the pressure from this reservoir forcing the destructible cap into its operative position and at the same time charging the ower portion o the cylinder 20. In this position of the parts the train is adapted to be cont-rolled from this car, itbeing readily seen that only a single safety apparatus need be lowered nto its operative position when the train is in motion and that one is upon the operatin -car.

As a c eck upon the motorman to deter mine the care with which he observes signals, I preferably blow into the destructible cap 3 or otherwise mark the same with a serial number or other means of identification, so that a'record of them can be kept. After one of these caps has been destroyed through apparatus is used in an elecfive or ten seconds, a failure of the driver to i mediately operate the three-way valve 15 carsopcrated by i caping see a signal he can imand close the valve 19, so as to move the piston-rod 4 until the openings 48 48 within the iston-rod 4 are within and closed by the xed plate 6. This prevents further escape of the fluid-pressure from the train-pipe l0 and permits of the ready application of another destructible cap in plac of the one broken without being interfered with by espressure; As soon as the brakes are set by the cap engaging with the fixed trip 1 the operator can, as previously stated, retract the piston 4 by means of three-way valve 15 and valve 19 and connections previously described and prevent the loss of more than a few pounds pressure from the train-pipe. It will thus be seen that should a train be sto )ped in a position so close to the fixed trip 1 t at the movable. portion of the safety a )paratus actually touched the fixed trip wit iout setting the brakes it is possible to(pass the trip with full control of power an that the train cannot be run for more than five or ten seconds without placing the safety apparatus in a position to automatically bring the train to a standstill iffor any reason the motornian fails to see the signal.

Having thus described my invention in connection with an electrically-propellcil ear, 9 5
